That Tiny Hole In A Plane Window
Two panes of plastic glass (perspex) are used to make the airplane windows. By itself, the inner glass could potentially shatter because of the huge difference in pressure inside and outside the cabin. The tiny hole allows the air to move between the cabin and the area between the two panes, equalizing the pressure between them. Now you know!
